Why each option
To logically organize VMs utilizing a new block storage system like a SAN, creating a storage tiering policy is the best way to optimize performance and cost.
Hard zones are related to Fibre Channel SAN security, defining which devices can communicate, but they do not logically organize VMs or data for storage utilization or performance optimization.
Creating LUNs (Logical Unit Numbers) is the act of provisioning block storage units, but it doesn't describe the logical organization or policy for how VMs efficiently utilize those LUNs across different tiers.
A storage tiering policy allows administrators to logically organize and distribute data, including VM data, across different types of storage media within a block storage system (e.g., fast SSDs for frequently accessed data, slower HDDs for less frequently accessed data). This optimizes performance for VMs by ensuring their active data resides on the appropriate tier while managing storage costs.
JBOD (Just a Bunch Of Disks) is a physical disk configuration, not a logical organization method for VMs or data within a block storage system for management or performance.
